Your engineering team on the ground in China.

For global technology companies that build from anywhere. We take hardware products from prototype to production through China's manufacturing ecosystem, and build the infrastructure your China operations run on.

Two practices. One team in China.

Hardware and infrastructure are both about systems that have to work in the real world. We do both, with the same engineering discipline.

Practice 01 Hardware

Hardware productization

From prototype to production.

For consumer and enterprise hardware alike. We work at the system level, where electronics, sensors, firmware and industrial design meet, and bring your product to production quality across the Yangtze River Delta and Greater Bay Area manufacturing hubs.

  • Engineering prototypes and design for manufacturing
  • Reliability engineering for the current generation
  • BOM strategy, cost targets and supply chain partners
  • Pilot production and the next-generation roadmap
Practice 02 Infrastructure

China infrastructure

The foundation your China operations run on.

For global companies with engineers, partners or offices in China. We architect networks and systems that connect seamlessly to your global stack, then hand them over or operate them for you.

  • Network architecture across sites and offices
  • Compliant cross-border connectivity to global platforms
  • China cloud deployment and ICP filing
  • Managed IT operations
02 · How we work

Built for remote-first teams.

/01

Scope

We define the outcome, deliverables, timeline and fee before work begins.

/02

Build

We execute on the ground in China and work with your team asynchronously, so you always know where things stand.

/03

Hand over or operate

You receive clear documentation and full ownership. When you need continuity, we stay on to operate and support.

04 · About

Infrastructure roots, hardware experience.

Annabai Tech was founded in Beijing by Bryan Huang. Before that, Bryan spent more than ten years working with the global teams of Google, Zynga, LinkedIn and Airbnb to build their China corporate infrastructure, twice supporting a China team from 10 to 300 people.

He has since led hardware products from concept to working prototype. As co-founder of a motorized fitness company, he defined the product, built the team and managed partners across the motor and its embedded firmware, a custom control board from circuit design to PCBA, mechanical structure and industrial design.

Earlier, he worked on the software and motor supply chain for a smart spin bike at a Xiaomi ecosystem company, and helped improve the identity hardware of a Silicon Valley startup. We bring both sides to every project: how systems are built, and how they are made.
